ABSTRACT = {Direct Numerical Simulations have been carried out to study the forced convection heat transfer of flow through
fixed prolate particles for a variety of aspect ratios <i>ar</i> = {5/4, 5/3, 5/1} with Reynolds number (Re) up to 100. Three
variations of the solid volume fraction <i>c</i> = {0.1, 0.2, 0.3} with four Hermans orientation factors <i>S</i> = {−0.5, 0, 0.5,
1} are studied. It has been found that changes in S cause prominent variations in the Nusselt number. In general,
Nusselt number increases with the decrease of <i>S</i>. For all three aspect ratios, the Nusselt number remains a linear
function of <i>S</i> at different c and Re. Therefore, it is concluded that, for heat transfer from prolate muti-particle
system, the effects of orientations cannot be ignored. A new correlation for Nusselt number has been developed for
arrays of prolate particles using the simulation data as a function of Re, <i>c</i>, <i>S</i> and <i>ar</i>.},
